the wii seems to be able to read the disc but when i press start its just black screen

Maybe the game disc is no good any more ? maybe thats why it was sold on ebay

hmm ok the GameCube Gekitou ninja Taisen 4 doesn't work as well ...

my Wii is V3.2E ... might this be the problem ?

seems i am not the only one with same problem

I got the free loader 2 day and I tried it then I put the ssbb and it showed the ssbb screen then I press the button the screen went black and the controllers turned off I dont no wats wrong

For the SSBB issue, the problem is that your wii if set to 60hz (480p/i). set it to 50Hz (576i?) and it will boot without problems. Then, you must set "Deflicker" in the SSBB options to OFF, that will allow you to run the game on 60Hz, or to make it stop stutter on 50Hz.
For Naruto EX, maybe I'm wrong but I think it didnt work with Wii video mode changer (trucha can't open iso ?). If that's the case, then it may not work with Freeloader too, which must be basically the same thing.
